CVE-2022-49329 vduse: Fix NULL pointer dereference on sysfs access

In the Linux kernel, the following vulnerability has been resolved: vduse: Fix NULL pointer dereference on sysfs access The control device has no drvdata. So we will get a NULL pointer dereference when accessing control device's msgtimeout attribute via sysfs: 132.841881 T3644 BUG: kernel NULL...

CVE-2022-49329: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: vduse: Fix NULL pointer dereference on sysfs access The control device has no drvdata. So we will get a NULL pointer dereference when accessing control device's msgtimeout attribute via sysfs: 132.841881 T3644 BUG: kernel NULL...

The vulnerability of the vduse_dev_ioctl() function in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the vdusedevioctl function in the drivers/vdpa/vdpauser/vdusedev.c file of the Linux kernel is related to memory allocation beyond the bounds of the allocated buffer. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...

kernel: vduse: fix NULL pointer dereference

A NULL pointer dereference vulnerability was found in the Linux kernel's VDUSE vDPA Device in Userspace subsystem. The vdusevdpasetvqaffinity callback can be invoked with a NULL cpumask value when deleting a vduse device. The code attempts to copy from this NULL pointer, causing a kernel crash...

SUSE CVE-2021-47604

In the Linux kernel, the following vulnerability has been resolved: vduse: check that offset is within bounds in getconfig This condition checks "len" but it does not check "offset" and that could result in an out of bounds read if "offset dev-configsize". The problem is that since both variables...
